Application filed June 8, 1910 Eerial No. 565,900.

To (ZZZ whom it may concern:

Be it known that I, HERMAN A. Minnie, a citizen of the United States, residing at. tayinond, in the county of Kandiyohi and State of illinnesota, have invented a new and useful Tire-Protector; and I do hereby declare the following'to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to a new and useful tire protector, adapted more especially for use in connection with automobile wheels, whereby the tires thereof may be In this specification and the annexed drawings, a particular design of device is adhered to, but the invention is not to be confined to this specific design.

The device in its actual reduction to practice may necessitate changes and variations, the right thereto belongs to the applicant, provided such changes and variations are compreheinled by the appended claims.

' In. the drawings: Figure 1 is an elevation of a segment of an automobile wheel, showing the protector applied thereto. Fig, 2 is a plan'view of the protector. Fig. 3 is a plan view of the protector, looking upon he inner face of the sections forming the protector showing a slight modification.

Fig. 4 is a sectional view on line 0t 1* 1g. 1. Fig. 5 is an enlarged detall-sectlonal view on line 5-5 'of Fig. 1. Fig. 6 is a sectional view on line (S(S otl ig. 5, taken transversely thereof.

(S designates the protector in its entirety, which is composed of a plurality of plates 7, which are joined together in sequence by means of rivetsS. These plates overlap one another, as shownclearlv in Fig. 1 and are designed to have individual movement, in order that the protector may accommodate itself to the various irregularities of the surface upon which the wheel travels, or to cater to the compression of the tire itself. These plates, upon their inner circumfershoe or taces,-are provided with ribs or projections 9, which engage the tire, in order to prevent the protector from creeping about the wheel anniilarly, or transversely.

As shown in the drawings, the plates are I of the tire.

' are carried by order to conform to the contour Two of the plates are joined together by means of bolts and nuts 11, which one ofthe plates, while the bolts penetrate the slots -12 of the other plate, and by screwing the nuts in one rcction or the other the two plates may loosened or tightened together.

The two plates, wh'ch are connected together by' a slot and bolt connection, and designated by the characters 15, are proarched, in

These angle plates are provided with aperr tures 19, as shown, and -through the apertures a threaded bolt or-rod 20 extends, one end of which being provided with a head, while to the otherend a nut '21 is threaded,

and by adjusting the nut the-two plates may be brought together orfart-her' apart, In place of this threaded rod or bolt, a turnbuckle 23 and two threaded rods 24 may be provided, as illustrated-in the drawings.

1 The outer faces of the plate are provided with ribs 26 running annularly about the protector, in order to prevent the wheel from skidding. It will be evident that when each of the two plates (which carry the adjustable and tightening device) have individual movements, the angle plates will have a pivotal action with regard to the members 17. From the above drawings, it will'be noted that a new and useful tire protector is afforded, having the necessary flexibility to cater to the compression of the tire and the irregularities of the ground.

The invention having-been set forth, whatis claimed as new and useful is 1. in a tire protector, a plurality of overlapping arched plates, having means to prevent skidding, slot and'pin or bolt connection, said two plates having guides, members arranged therein, angle plates pivoted to the members, and means coiiperating with the angle two ot' the plates having a v therein, angle plates pivoted to the men1- In testimony whereof I have signe d inyn hers, a threaded rod penetrating the angle name to this specification in the presence of plates, and means threaded to the rod in ortwo subscribing Witnesses.
